Toyota Motor Corp. is developing magnesium batteries are expected to store electrical energy twice that of lithium-ion.Penelitian cells was carried out at Toyota's technical center in Ann Arbor, Michigan.Baterai magnesium will be part of a vigorous development of electric cars of Toyota, said Jeffrey Makarewicz, a Toyota engineer. "the transition from the nickel-metal hydride to lithium ion, is essentially to increase the storage capacity has doubled," he said."Lithium ion theoretically, under ideal conditions, has a capacity of about 2,000 kilowatt hours. It's still not enough to make the batteries needed for electric vehicles and hybrid-electric future. "
Vehicles with magnesium batteries or alternative materials may only be ready by 2020, says Makarewicz.
Meanwhile, Nissan's flagship electric car, Leaf, targeting sales of up to 500,000 units in America.
However, Toyota set a lower figure because during the research process batteries, electric car (not hybrid) will still have many limitations.
In addition to magnesium, the car maker in the U.S. also looked at other materials such as aluminum and calcium.
